Relevant text: Serving as the FTC's infrastructure expert, he testified on technical aspects such as service speed and user perceptions of responsiveness, assessing potential competitive harms from reduced incentives for innovation post-acquisition; his declaration, referenced in court filings, emphasized empirical metrics over speculative harms.[49][50]
Paragraph 756: Tim Bray, the FTC’s proffered infrastructure expert, opined that “[u]sers’ perceptions of how quickly an online product responds to requests is an important component of the quality of their experience,” and that the delay between a user request and an online product’s response is commonly referred to as latency. Ex. 288 at ¶ 98 (Bray Rep.). Mr. Krieger testified that Instagram saw a “significant latency reduction post-Instagration,” a term referring to Instagram’s migration to Meta’s data servers. Ex. 153 at 76:24-77:5, 287:3-20 (Krieger Dep. Tr.). He prepared a presentation in 2014 stating that there was a “75% latency reduction in our core ‘hot path’ in rendering feeds” after the integration.
With these sources in hand I think I am convinced of Tim's original point; I first looked at that ftc document and didn't see anything about user responsiveness in it.
The fact that it's not mentioned and that the main points he made in that summary have nothing to do with user responsiveness is evidence that Grok did a crap job summarizing his role in the FTC's cas, right?
